Kate Middleton reveals why she gets teased by the royal family

In the ITV documentary Our Queen at Ninety, which celebrates Queen's Elizabeth's milestone birthday on April 21, the 34-year-old princess reflects on how the monarch has helped her adjust to royal life since marrying Prince William in 2011.

"She's been generous and not forceful at all in her views, Kate says of the queen. "And she's really been there in a gentle guidance for me."

While from the outside, the Duchess of Cambridge seems to have royal life down pat, she goes on to claim that she actually gets teased by the family for her conversation game at official events!

"There's a real art to walkabouts, everybody teases me in the family that I spend far too long chatting," Kate says. "I still have to learn a little bit more, and to pick up a few more tips I suppose."

The Duchess wore L.K. Bennett separates for the ICAP charity day where she and William haggled with donors to raise money for charity.
